Process Involved in Choosing a Measurement Tool for Variables in Research

Process Involved in Choosing a Measurement Tool for Variables in Research According to Santayana (2008, p.1), â€Å"measurement is at the core of doing research†. Generally, after conducting research, researchers have to reduce their finding to numbers in order for people to understand their study findings. Such measurements are exceptionally essential in the measurement of hypotheses. Researchers therefore must come up with sound measurement tools for both independent and dependent variables.Advertising We will write a custom essay sample on Process Involved in Choosing a Measurement Tool for Variables in Research specifically for you for only $16.05 $11/page Learn More Measurement is not as easy as it sounds. It is composed of four basic principles. The first two, conceptualization and operationalization are a bit simple. The other two are more advanced and complicated. They include determining the levels of measurement and measuring validity and reliability. Conceptualization involves defining a concept. Thus, researcher s must define that particular concept in a manner that is understandable by the scientific community. Researchers are allowed to borrow conceptualization from their predecessors and other researchers. On the other hand, operationalization involves making the conceptual definition more precise. This often involves linking the conceptual definition to one or more indicators. The indicators chosen must reflect observable reality in numbers. For example, in the parent involvement study, the conceptual definition is ‘parents’ involvement’. However, the operational definition is ‘parents’ role construction’. It is also important when giving an operational definition to establish the unit of analysis. In addition, a researcher needs to evaluate the level of measurement. Santayana (2008, p.1) indicates that â€Å"the level of measurement is the precision by which a variable is measured and there are four levels of measurement namely nominal, ordinal, interval, and ratio†. The four levels are named from the lowest to the highest. On the other hand, Stevens (1951, p. 1) states that â€Å"everything that can be measured falls in the aforementioned levels and the higher the type, the more the precision in measurement†. Variables that are categorical in nature usually fall in the nominal level while those that have significant importance fall in the ordinal level. Variables that have significant distances between their ranks fall in the interval level. On the other hand, variables that have fixed intervals and a fixed reference point are grouped in the ratio level. It is for these reasons that Creswell (2011) holds the opinion that researchers must define their variables conceptually and operationally while putting into account the levels of measurement since these factors eventually determine how the data collected is analyzed. In the parent involvement study, ‘parents’ involvement’ falls in the ord inal level.Advertising Looking for essay on education? Let's see if we can help you!

Validity can be measured using four methods namely face, content, criterion and construct. On the other hand, reliability can be estimated using the following methods test retest, multiple forms, inter rater, and split half. Therefore, in order to locate an instrument that is to be used to measure a given variable, a researcher must put into account a number of factors. First and foremost, according to Slavin (1984), the researcher must define his concept conceptually and operationally. After that, the researcher must establish the level of measurement in which his or her variable falls. In addition, the researcher must detect the rationales he or she will use to estimate validity and reliability. The achievement of this goal relies on having proper concept ual and operational definition and the establishment of the level of measurement of the variable. References Cresewell, J. (2011).

How to Find a Career That Will Give You a Sense of Purpose

How to Find a Career That Will Give You a Sense of Purpose Most people would agree that having a sense of purpose in a job makes them feel more productive and happier because then a job seem less like work. In addition, helping others seems to be more important than the money earned in a job. That produces motivation and a willingness to put in extra effort. Taking a look at what jobs have the highest and lowest satisfaction rates according to surveys is an interesting way to assess what job may be right for you. PhysiciansPhysicians in the health care field showed the highest satisfaction rate in their jobs with a score of 95.5 percent. Neurosurgeons, along with cardiothoracic surgeons, OB/GYNs and anesthesiologists were at the top of the job satisfaction list. Not only do these health care jobs offer high pay, they also offer the bonus of a contribution to society by treating the sick and saving lives.Self-Employed Business OwnersThis group encompasses entrepreneurs, business owners and contractors. With a job satisfaction rating of 93.3 p ercent, the people in this group had the highest rating for work environment, including a feeling of openness and a sense of trust. The accomplishment attained in these types of jobs is an important aspect of achieving satisfaction.TeachersTeachers, including teaching assistants and teachers of special education, came next at 91.1 percent. Almost 70 percent said they were thriving, and the teachers reported that they had been happy within the past 24 hours, by laughing, smiling or having experienced joy in their lives.Jobs Requiring Professional TrainingComputer programmers, architects and other professions that require professional training reported a 90.4 percent satisfaction with their jobs. Because of their training, they were placed in jobs with responsibility and the ability to see the outcome of their efforts.Managerial JobsThose in managerial jobs scored their work environments high and reported their satisfaction level as 90.3. Well over half of those surveyed said their su perior in the company treated them like an equal, which was a higher rating than all the other professions that were surveyed.Jobs With the Lowest SatisfactionThose who work in jobs where morale tends to be lowest are also the most dissatisfied with their jobs. Workers in fast food restaurants show the least amount of satisfaction in a job, according to PayScale, with 25 percent saying that their jobs make the world more unpleasant. Coming in second were pickers at 21 percent. These workers spend their days working in warehouses to ensure that purchasers receive their packages. The monotony of the job, combined with staying in a warehouse all day may contribute to their dissatisfaction. Floor supervisors for table games at casinos also said their jobs made the world more unpleasant. Although this type of job is fairly high paying, watching people lose money at the game tables every day must be difficult for some.Finding a Satisfying JobSatisfaction in your job and feeling that you a re making a contribution makes it more likely that you will be happy with a position, no matter what it is. Some people are motivated by pursuing a career with an eye toward advancement, while others believe that passion for what they are doing make a difference. Having a good attitude, challenges in your work that encourage you to improve, variety in the tasks you are expected to do and a feeling of accomplishment at the end of the day contributes to your sense of satisfaction in a job.TheJobNetwork helps you job hunt by noting your skills and interests to send you job alerts when positions of this type become available. After you sign up for job match alert, all you have to do is fill out your qualifications and what types of jobs you are seeking. If you prefer, you can use the job site to search yourself, saving yourself the time from looking at multiple sites to find that great job.

Abortion Essay Example | Topics and Well Written Essays - 1000 words - 10

Abortion - Essay Example According to Rank’s Persuasion Mode, the persuaders on the two position take the schemas of intensify and downplay. (Hitchcock, David, and Bart, 15) In the January, 20, 2014 article written by Jeremy W. Peters, though the headline of the paper suggests that â€Å"Both sides of the abortion issue expressed their views at the last year’s March for Life in Washington†, the emphasis has been laid on Pro Life. The expression presented is that â€Å"there will be a demonstration of the annual anti-abortion, and should the demonstrators need a lift after the demonstration, then they may hope on the free shuttle that would be provided by the republican. From these preceding connotation my The New York Time columnist, clearly, it would be said that the writer is using intensify. Emphasis is created in how supporters of the abortion are not just getting support from significant party like Republican, but also with the benefits presented. In the subsequent paragraph, the writer makes statements that create intensity in the weaknesses of the position presented by Jill Cowan of Los Angeles Times. According to the commentary by Jill Cowan, the column is presented with the Headline: â€Å"State allows Hoag Hospital to refuse elective abortion†. Jill notes that Hoag Hospital had successfully managed to impose the ban on abortion considering that they had made a partnership with the Catholic healthcare providers, and considering that they must also appreciate the demands of the State, they will have no option but to refer their clients to other places where they can get abortion services. In relation to what was presented by The New York Times, it sounds clear that the Los Angeles Times is presenting some issue which evidently does not appreciate the health of the mother. New York Time has tried to intensify the weakness of the position taken by Los Angeles Times in this case. According to the theory of Rank’ s Model, the

Testing Drugs On Animals Essay Example | Topics and Well Written Essays - 1000 words

Testing Drugs On Animals - Essay Example The American Medical Association has stated that it believes that research involving animals is essential to maintaining and improving the health of human beings. They point out that all advances in medical science in the 20th century, from antibiotics to organ transplants, has been achieved either directly or indirectly through the use of animals in laboratory experiments. Arguments for animal experimentation may question the morality, necessity, and validity of these studies. The moral issue on animal experimentations concerns the need to protect human life and to improve the quality of life. The gains in human health and well being outweigh the cost in animal suffering which nonetheless should be kept to a minimum, in this viewpoint. It would be immoral to conduct such tests on humans, and so animals serve as our stand-ins for many kinds of testing and research. Those who support animal testing may care deeply about animals but don't place them on an equal status with humans. Research on animals may be deemed necessary for a variety of reasons: to develop vaccines and treatments and cures for diseases, to ensure that new products are safe to use. Such as making sure that they won't blind us, burn our skin, or even kill us and to help students, especially prospective doctors, veterinarians, and so on, learn their way around a body. Animals do make good research subjects for many purposes and research on them can tell us a great deal about ourselves. Animals are, in many ways, biologically similar to humans and are susceptible to many of the same health problems. Some species may serve as particularly good models for certain aspects of human health or physiology. Much of what we know about the immune system, for example, has come from studies with mice, and much of what we know about the cardiovascular system has come from studies with dogs. Many heart surgery techniques, such as coronary bypass surgery, artificial heart valve insertion, and pacemaker implants, were studied first in dogs before being used in people. (Jean Swingle Greek, DVM and C. Ray Greek, MD) Animals may make even better research subjects than humans in some regards. Furthermore, scientists can control certain aspects of an animal's environment, diet, temperature, lighting, and so on, more easily than would be possible with people. Supporters of the use of animals in research argue that alternative methods can't fully replace the use of animals, and may never do so. Neither cells grown outside a body nor computer programs can predict the complex interactions that occur in an entire living system. Countless medical treatments, techniques, and technologies have come about, at least in part, through animal experimentation. The development of immunization against such diseases as polio, diphtheria, mumps, measles, rubella, pertussis, and hepatitis all involved research on animals, as did the discovery of insulin and the study of diabetes. Animal research also has played a part in the development of organ transplantation, hip replacement, chemotherapy, cardiac pacemakers, coro nary bypass surgery, ongoing efforts to understand and treat AIDS and Alzheimer's disease, and more. Arguments against animal testing may also question the morality, the necessity, or the validity of these studies. That is, whether we have the right to perform such

Hybrid Cars :: Gasoline Electric Hybrid Automobiles

Hybrid cars: Abstract: A hybrid car, also known as an HEV or hybrid electric vehicle, is an automobile that is powered by two sources; an internal combustion engine, and an electric motor. HEV’s need plugs, as they are amply charged by the movement of the wheels and storing the kinetic energy that is generated through a process called regenerative braking. Cars have been accepted as a solution to the current pollution problems that we face, as they offer lower emissions than gasoline automobiles. Some hybrid cars produces around 90% less pollutants than regular cars. With cars with this system, a hybrid car can cross longer distances than normal ones with less use of gasoline. They can get up to 55-60 mpg in city driving, while a typical SUV might travel just 15-20 mpg. Also there are 2 types of cars: the first type is the series, and the second type is called the parallels Hybrid electric vehicle A hybrid electric vehicle (HEV) is a vehicle which combines a conventional propulsion system with an on-board rechargeable energy storage system (RESS) to achieve better fuel economy than a conventional vehicle without being hampered by range from a charging unit like a battery electric vehicle (BEV), which uses batteries charged by an external source.)The different propulsion power systems may have common subsystems or components. Regular HEVs most commonly use an internal combustion engine (ICE) in tandem with electric motors to power their propulsion system. Modern mass-produced HEVs prolong the charge on their batteries by capturing kinetic energy via regenerative braking, and some HEVs can use the combustion engine to generate electricity by spinning an electrical generator to either recharge the battery or directly feed power to an electric motor that drives the vehicle. Many HEVs reduce idle emissions by shutting down the ICE at idle and restarting it when needed. An HEV's engine is smaller and may be run at various speeds, providing more efficiency. HEVs became widely available to the public in the late 1990s. HEVs are viewed by some automakers as a core segment of the future automotive market. Technology The varieties of hybrid electric designs can be differentiated by the structure of the hybrid vehicle drivetrain, the fuel type, and the mode of operation. In 2007, several automobile manufacturers announced that future vehicles will use aspects of hybrid electric technology to reduce fuel consumption without the use of the hybrid drivetrain. Regenerative braking can be used to recapture energy and stored to power electrical accessories, such as air conditioning.

Toy Recall

Mattel is multinational toy company that has been beleaguered by problems involving massive toy recall. Indeed, the company has been announcing product recalls and providing details about them since 1998. In 2007, wooden toys were ordered recalled by the state Department of Consumer Protection because the toys were found to have high lead content. Moreover, the excessive amount of lead found in the toys was considered violations of the federal prohibition on the use of lead paint on children’s toys (U.S. Consumer Product Safety Commission, 2007). Apparently, the toy was already sold in several stores. Thus, the Department of Consumer Protection instructed customers to return the purchased items to stores for a cash refund (Krechevsky, 2007). Mattel is taking a beating with the repeated product recalls of Chinese-made toys, due to excessive levels of magnet and lead content. The staggering number alone of the toys recalled, coupled with the frequency and short duration in between recalls, is sure to cause damage to the company’s credibility and financial performance (Microsoft, 2008). Reports would show that in the previous year, Mattel recalled 1.5 million Fisher-Price infant toys to be sold all over the world. A few weeks later, Mattel announced another recall order of 9 million toys, such as Polly Pocket dolls, â€Å"Cars† movie souvenir products, and Barbie dolls. Other popular toys that are included in the toy recall are Tanner play sets and action figures of Batman and One Piece Triple Slash Zolo Roronoa action figures. These toys, which were all manufactured in China, are feared for having lead-paint and small magnets that could be swallowed (Microsoft, 2008). Several injuries related to the recalled toys had been reported in the United States, which include the death of one child and the surgery of 19 children since 2003, as a result of the swallowing of little magnets found in the toys. Children who swallow more than one magnet are in danger of intestinal perforation, blockage, or infection caused by the magnet’s attachment to each other. Intestinal perforation requires surgery, and could be fatal (Microsoft, 2008). On the other hand, the high levels of lead content in China-made toys present a different risk. It is not necessarily dangerous for children’s toys to have lead paint. However, there is a limit to the lead content of toys because there should only be a maximum of 0.6 percent of lead that is accessible to users. Children who are exposed to more than 0.6 percent of lead could ingest the toxic substance (Microsoft, 2008). These frequent and massive toy recalls would create a huge dent on the company’s credibility among consumers, specifically parents. This would easily translate into huge losses in terms of profit. Thus, Mattel is trying very hard to convince parents not to lose trust in the company. The company is undertaking campaigns such as full page ads at popular newspapers like the Wall Street Journal, USA Today, and New York Times, in order to convince parents that they should still be trusted to provide entertaining and safe toys for children (Microsoft, 2008). Officials of the company say that they started investigating as soon as they learned of potential problems with the toys in late July of the previous year. Bob Eckert, the chief executive of Mattel, declared in a press conference that the company is exerting effort to beef up its oversight and testing procedures in its production processes. Thus, they expect to recall more toys to protect the public. Testing in the high levels as the company is currently doing, it cannot be guaranteed that there would be no more recalls this year. In order to help consumers who may have concerns and questions about toy recalls, Mattel set up an online site where such concerns could be ventilated (Microsoft, 2008). The company’s response to the toy recalls is to counteract the damage done. Thus, they spent resources in printing huge and expensive ads in popular newspapers in order to reach out to their primary consumers, or the parents. They try to convince parents that their foremost priority is the safety of the consumers’ children, and the toy recalls are steps in the right direction towards protecting children. Mattel’s lack of objection, and instead, full cooperation and support for the toy recalls shows that the company is taking full responsibility for the situation, and that they are not shirking from their responsibility to the consumers. The company’s actions send a strong message that they know that something is wrong, but they are doing all that are necessary to address the problem. Moreover, the establishment of a hotline and a website that would provide relevant information to all concerned is a responsible initiative that shows how serious Mattel is in helping out consumers. In the given situation, Mattel could not have handled the situation in a better manner. An irresponsible manager would try to keep the controversy under wraps in order to avoid humiliation and damage to the company’s reputation. However, it is better to address the issue head-on in order for the company to maintain the customers’ trust and confidence. If I were an official for Mattel, I would put more vigor to the campaign and marketing of Mattel products. I would not stop at newspaper advertisements and appeal to the intellect of parents; rather, I would again tap into the interests of children so that they would want Mattel’s products. This way, parents would feel pressure from children to reconsider Mattel as a toy producer. Before Mattel took a definite course of action, it was possible that they considered to keep the controversy a secret. They could have taken a risk in not recalling products and simply hope that no injury would result. They could have chosen to be irresponsible. However, such alternative action would have resulted in more damage in the credibility of the company. If such act were discovered, it would make the company appear greedy and selfish, without regard for the health and safety of its consumers. Therefore, Mattel’s strategy of coming out in the open, supporting the recalls, and providing support to consumers, is the best strategy possible in the given circumstances.
